What is the temperature when water changes from gas to a liquid?

Answer 1

Temperature At Which Water Changes into gas

Water molecules can change their status from liquid to gas (evaporation) at any temperature over 0 Celsius degrees.


Water molecules can change their status from solid to gas (sublimation) at any temperature below 0 Celsius degrees.

At sea level water boils 212 Fahrenheit or 100 celsius. When water boils, all its molecules change their status from liquid to gas.

Water (H20) in liquid form at sealevel (where the pressure is 1 Atmosphere) will boil into a gas at 100 degrees Celcius, or 212 degrees Fahrenheit. This number will change slightly depending on one's altitude, as lower pressures will induce a lower boiling point. 212 Degrees Fahrenheit or 100 degrees Celsius at standard atmospheric pressures. It is extremely important to know that the boiling point of a liquid is based on it's pressure. at 100,000 feet it might be 40 degrees.

So we would need a Barometer, and/or possibly a Micron gauge to correctly answer the question.

Answer 2

Water vapor condenses (changes from gas to liquid) at 212 Fahrenheit or 100 Celsius
